2 - 8 DS2208 Digital Scanner Product Reference Guide
2. Press and hold the trigger until either:
a. The digital scanner reads the bar code. The digital scanner beeps, the LED flashes, and the scan line turns
off.
Or
b. The digital scanner does not read the bar code and the scan line turns off.
3. Release the trigger.
Aiming
When scanning, the digital scanner projects a red scan line which allows positioning the bar code within its field of
view, omnidirectionally. See Decode Ranges on page 2-8 for the proper distance to achieve between the digital
scanner and a bar code.
Figure 2-6 Scanning Orientation with Aiming Line
The aiming line is smaller when the digital scanner is closer to the symbol and larger when it is farther from the
symbol. Scan symbols with smaller bars or elements (mil size) closer to the digital scanner, and those with larger
bars or elements (mil size) farther from the digital scanner.
The digital scanner beeps to indicate that it successfully decoded the bar code. For more information on beeper
and LED definitions, see Table 2-1 and Table 2-2.
